+/** \ingroup libusb_misc
+ * How to add a new \ref libusb_strerror() translation:
+ * <ol>
+ * <li> Download the latest \c strerror.c from:<br>
+ *      https://raw.github.com/libusb/libusb/master/libusb/strerror.c </li>
+ * <li> Open the file in an UTF-8 capable editor </li>
+ * <li> Add the 2 letter <a href="http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes">ISO 639-1</a>
+ *      code for your locale at the end of \c usbi_locale_supported[]<br>
+ *    Eg. for Chinese, you would add "zh" so that:
+ *    \code... usbi_locale_supported[] = { "en", "nl", "fr" };\endcode
+ *    becomes:
+ *    \code... usbi_locale_supported[] = { "en", "nl", "fr", "zh" };\endcode </li>
+ * <li> Copy the <tt>{ / * English (en) * / ... }</tt> section and add it at the end of \c usbi_localized_errors<br>
+ *    Eg. for Chinese, the last section of \c usbi_localized_errors could look like:
+ *    \code
+ *     }, { / * Chinese (zh) * /
+ *         "Success",
+ *         ...
+ *         "Other error",
+ *     },
+ * };\endcode </li>
+ * <li> Translate each of the English messages from the section you copied into your language </li>
+ * <li> Save the file (in UTF-8 format) and send it to \c libusb-devel\@lists.sourceforge.net </li>
+ * </ol>
